InputStream to JsonObject - GSON
提问by JochemQuery
I've a lot of trouble converting a result from this api to a JsonObject.
将此 api 的结果转换为 JsonObject 时遇到了很多麻烦。
The "result" stays null no matter what I try to do.
无论我尝试做什么，“结果”都保持为空。
URL url = new URL(urlString);
InputStream input = url.openStream();
Reader reader = new InputStreamReader(in, "UTF-8");
JsonResult result = new Gson().fromJson(reader, JsonResult.class);

JsonResult 类
public class JsonResult {
private String status;
private Meta meta;
private ArrayList<Player> players;
}
class Meta{
private String count;
}
Json:

{"status":"ok","meta":{"count":12},"data":[{"nickname":"DataBase","account_id":500566109},{"nickname":"database007","account_id":514382449},{"nickname":"Database04","account_id":504367425},{"nickname":"database08","account_id":515081772},{"nickname":"database1","account_id":503282284},{"nickname":"database1221","account_id":506709044},{"nickname":"database123","account_id":508409172},{"nickname":"database1337","account_id":501661259},{"nickname":"database169","account_id":503884400},{"nickname":"database2","account_id":504337382},{"nickname":"database93","account_id":518691821},{"nickname":"databaseking66","account_id":505911069}]}
